MIT discovery unleashes solar revolution
First, MIT scientists recharged batteries wirelessly. Now they can mimic essence of plants' energy storage system.
In a leap that could transform solar power from a marginal, boutique alternative into a mainstream energy source, Massachusetts Institute of Technology (MIT) researchers have overcome a major barrier to large-scale solar power: storing energy for use when the sun doesn't shine.
Until now, solar power has been a daytime-only energy source, because storing extra solar energy for later use is prohibitively expensive and grossly inefficient. With today's announcement, MIT researchers have hit upon a simple, inexpensive, highly efficient process for storing solar energy.
Now a team led by Daniel Nocera at MIT has found a catalyst that uses cheap, abundant metals—cobalt and phosphorus—and works at an environmentally friendly neutral pH to release oxygen from water.

Last year , MIT scientists developed the basis for a technology that could bring wireless convenience to battery recharging, allowing you to pack all those adapters into a drawer for good. The MIT team, with members from the school's physics, electrical engineering, and computer science departments, along with its Institute for Soldier Nanotechnologies [http://web.mit.edu/isn/], adapted known qualities of magnetically coupled resonance to transmit electricity from a power source to light a 60 W light bulb 7 ft away.
Annual Salary Survey
After almost a decade of uncertainty, the confidence of plant floor managers is soaring. Even with a number of challenges and while implementing new technologies, there is a renewed sense of optimism among plant managers about their business and their future.
The respondents to the 2014 Plant Engineering Salary Survey come from throughout the U.S. and serve a variety of industries, but they are uniform in their optimism about manufacturing. This year’s survey found 79% consider manufacturing a secure career. That’s up from 75% in 2013 and significantly higher than the 63% figure when Plant Engineering first started asking that question a decade ago.
